多功能脉冲恒流源的研究

Research of Multifunction Pulsed Constant Current Supply

针对微弧氧化、离子渗氮等离子体表面处理工艺中有时需要电流恒定这一特点,提出一种新型的多功能脉冲恒流源,此电源既可以实现峰值电流恒流也可以实现平均值电流恒流,并且可以进行实时的转换。该电源的设计思想和具体实现方法在文中有详细的阐述,且其2种功能在不同的参数条件下均能稳定工作。另外,将此电源用于部分工艺实验后也产生了较好的效果。

According to the feature of constant current demanding in some Plasma surface treatment crafts,a new type of pulsed constant current supply of multifunction is proposed. Constant current of peak and constant current of average both can be realized by using this supply, real- time changing as well. The design idea and detailed implement methods are explained in this paper, and under different circumstances the two functions can also work steadily. In addition, some good effects have been discovered in latter experiments.
